The invention relates to a tunnel construction unit, in particular to a tunnel face dust-extraction unit. According to the tunnel face dust-extraction unit, the problem that the effect of a traditional tunnel dust-extraction method is not good is solved. The tunnel face dust-extraction unit includes a waterproof board trolley, a press-in type ventilating wind pipe, a dust-extraction device, a smoke concentration detector and a controller; an arched door frame of the waterproof board trolley is provided with a dust shielding cloth in a hanging mode; the press-in type ventilating wind pipe penetrates through the dust shielding cloth; the dust-extraction device includes a dust shielding roller shutter, a smoke flow guiding pipe, a collision-type inertial dust remover, a bag-type dust removerand a dust-extraction water tank; the lower part of the arched door frame is sealed through the dust shielding roller shutter, a jet fan is arranged in the smoke flow guiding pipe, and the collision-type inertial dust remover, the bag-type dust remover and the dust-extraction water tank are all arranged on a main platform; the smoke concentration detector is arranged at the front end of the smokeflow guiding pipe; and the controller is used for controlling the dust-extraction device and is arranged on the waterproof board trolley. The tunnel face dust-extraction unit is suitable for dust-extraction work in tunnel construction.
Description
technical field [0001] The invention relates to a tunnel construction device, in particular to a tunnel face dust removal device. Background technique [0002] Dust produced by tunnel blasting excavation and primary sprayed concrete pollutes the tunnel air and seriously endangers the health of workers. The traditional dust prevention and removal methods for tunnels are mainly based on measures such as tunnel watering, air duct ventilation, and roadway ventilation. Dust reduction, relying on the self-weight of the long-distance dust in the tunnel, or expelling the smoke and dust gas to the outside of the tunnel by wind force, this cleaning process is likely to pollute the entire tunnel, resulting in a decline in the overall air quality in the tunnel, and secondary dust is very likely to occur; second, large-scale Water sprinkling and dust removal can easily cause water vapor atomization, and there are hidden dangers in electricity consumption. However, due to the long ventil...
